The genes were sourced from Chlamydomonas rienhardtii and synthesised.
This composite part is made up of various genes that form a part of the chlorophyll biosynthesis pathway. ChlI1 and ChlI2 forms a Mg-chelatase complex which catalyzes the insertion of magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX. ChID forms an ATP dependent complex with ChlI1 and ChlI2 before acting of protoporphyrin. GUN4 is a tetrapyrrole-binding protein which controls the production of Mg-protoporphyrin IX found only in aerobic photsynthetic organisms. It is thought to participate in plastid-to-nucleus signalling by regulating Mg-protoporphyrin IX synthesis. Finally, ChlH is a chloroplast precursor which plays a role in the regulation of light in chlorophyll biosynthesis. CTH1 is a functional protein that is developed in the prescense of oxygen or copper. It catalyzes Mg-protoporphyrin IX monomethyl, which converts to divinyl protochlorophyllide in the presence of NADPH and O2.

The Plac insert was PCR'd from the MG1655 strain of E.coli K12.
Inverting regulatory region controlled by LacI (<bb_part>BBa_C0010</bb_part>, <bb_part>BBa_C0011</bb_part>, etc.) The pLac regulatory region is a 243 base-pair sequence with standard BioBrick prefix and suffix sections on its ends. It contains two protein binding sites: CAP, which is generally present in E.coli and is assocciated with cell health and availability of glucose., and LacI, the Lac inhibitor <bb_part>BBa_C0010</bb_part> which binds in an dimerized cooperative manner to inhibit the transcription of the protein that follows. In the presence of lactose or IPTG, an analog of lactose, LacI is unable to correctly bind and inhibit transcription. This allows <bb_part>BBa_R0010</bb_part> to be used as a inverter or as a detector of lactose or IPTG.
LacI binds to this regulator. This part is incompatible with species containing active LacI coding regions. Lactose and IPTG disable the operation of LacI and this regulator. This part is incompatible with environments containing lactose or lactose analogs.
